The bark does not have displacement but has some bump map. I wanted to keep it smooth but I didn't want to get too involved with that (yet). When I try to get something for use in TG2 I'll go further. Maybe do something in 3D Coat to get some nice textures on bigger trunks.
Yeah, Blender 2.5 is going to be very cool. I don't care what anyone says about Blender, it is a way cool app and getting better all the time. I find it hell to work in a lot of other apps. I don't know what the big issue is with the UI. It is very simple and easily configured.
